报告摘要：
The El Nino Southern Oscillation (ENSO) is the most important mode of natural climate variability. Its dynamics, characteristics and future climate change are complex and the focus of some of the on going research. This talk will present some of the current areas of ENSO research. It will illustrate interesting dynamics that ENSO shows and illustrate some of the open questions. ENSO is further related to interactions with the other ocean basins that contribute to the complexity of ENSO. Finally, the observed tropical Pacific mean state changes are mark by a strong La Nina like pattern, with a near absence of any warming in the last 40yrs. This is in strong contrast to CMIP model projects and is likely to present the first substantial failure of large-scale CMIP model projections. Thus, it suggests that CMIP model are fundamentally biased in their projections of tropical Pacific mean state changes. The talk will discuss to what extend understanding ENSO dynamics may help in understanding this unusual development.
